Name of the Vulnerable Software and Affected Versions

The issue is related to errors in resource release in the MySQL Server component, specifically in the DDL subcomponent.

The vulnerability can be easily exploited by a high-privileged attacker with network access via multiple protocols.

As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
